-Subject: fix build regression in arm atomics asm with new binutils
-
-binutils commit bada43421274615d0d5f629a61a60b7daa71bc15 tightened
-immediate fixup handling in gas in such a way that the final .arch of
-an object file must be compatible with the fixups used when the
-instruction was assembled; this in turn broke assembling of atomics.s,
-at least in thumb mode.
-
-it's not clear whether this should be considered a bug in gas, but
-.object_arch is preferable anyway for our purpose here of controlling
-the ISA level tag on the object file being produced, and it's the
-intended directive for use in object files with runtime code
-selection. research by Szabolcs Nagy confirmed that .object_arch is
-supported in all relevant versions of binutils and clang's integrated
-assembler.
-
-patch by Reiner Herrmann.

-Subject: [PATCH] in dns parsing callback, enforce MAXADDRS to preclude
- overflow
-
-MAXADDRS was chosen not to need enforcement, but the logic used to
-compute it assumes the answers received match the RR types of the
-queries. specifically, it assumes that only one replu contains A
-record answers. if the replies to both the A and the AAAA query have
-their answer sections filled with A records, MAXADDRS can be exceeded
-and clobber the stack of the calling function.
-
-this bug was found and reported by Felix Wilhelm.
